Liongard provides an attack surface management platform designed specifically for managed service providers (MSPs). The company's platform automates the documentation and monitoring of IT system configurations across multiple client environments, enabling MSPs to track changes, identify security risks, and maintain visibility across their customers' technology stacks. The platform includes several key capabilities: automated configuration documentation, real-time monitoring of IT infrastructure changes, security and best practice assessments, and integration with PSA tools like ConnectWise Manage. Liongard's system uses what the company calls "Inspectors" to collect data from various technology systems including Microsoft 365, DNS records, network equipment, and other infrastructure components. Recent product developments include LiongardIQ for attack surface management, ThreatImpactIQ for AI-powered vulnerability risk prioritization and remediation, and HunterX for MSP growth initiatives. The company acquired Darklight's vulnerability prioritization platform in 2025 to enhance its proactive cybersecurity capabilities. Liongard's platform maintains historical timelines of configuration changes, allowing MSPs to investigate incidents by reviewing what changed and when. The system generates alerts that can be automatically converted into service tickets, helping MSPs shift from reactive to proactive service delivery. The company was founded by Joe Alapat and Vincent Tran, both CISSPs, and is currently led by CEO Michelle Accardi.
